Application filed September 20, 1921.

, To all whom it may concern:

In the accomplishment of these objects vT have evolved a headlighthaving certain novel features of construction, combinations andrelations of parts as disclosed in the following specification andillustrated in the aocom anymg drawing. I

In tie drawing referred to, l have illus trated typical embodiments ofthe invention in which Figures 1 and 2 are longitudinal sectional andfront views respectively of one form of the invention, and in whichFigure 3 is a longitudinal sectional View of a slightly modified form ofthe device.

In both the forms shown, the lamp house or easing 5 is made rectangularand substantially square, having the upper portion of its front end opento provide a rectangw lar outlet 6 for the beam of light and the lowerportion of such front end covered by an upright wall 7 of a heightsufficient to extend above the filament of the lamp.

The lamp is indicated at 8, and the same is suitably supported in thebottom of the casing with its filamentbelow the upper edge of the blindor shield 7 so that such filament will not be visible from the front ofthe lamp structure.

The reflector which is located over and in back of the lamp consists ofa series of concave reflector stri s 9, 10, 11 and 12 offset one infront 0 the other and each arranged to reflect the light which itcollects substantially horizontally so as to form a beam whoseconstituent rays are substantially horizontal, as indicated by the lines9*, 10, 11* and 12*. These reflector strips may constitute in effect theoflset sections of the upper half of a parabolic curve.

In the first form of the invention, the lamp is shown as set quiteclosely behind Serial No. 501,919.

the filament covering shield, whereas, in the second form, the lamp isset further back and the reflector sections are inclined more nearlyparallel to the horizontal. With this latter form, on account of thereduced angle of the reflecting faces, the possibility of any glareresulting from looking directly at the reflecting surface, is lessened.

The lower half of the lamp in the illustration, is silvered or providedwith a suitable reflector 13 so as to reflect the light emanating fromthe front of the lamp backwardly and upwardly against the beamreflecting strips.

In both the forms illustrated, the lamp is supported in a forwardlyinclined position so as to expose a full clear halfof the lamp to thereflector, the lamp socket 14.- being for such purpose set at anincline, such as indicated.

The reflector strips preferably extend straight across the entire widthof the lamp casing so as to collect all possible light and so as totransmit a wide horizontal light beam. Aside from the reflecting strip,the entire interior of the lamp house is prefably darkened. Thisdarkening may even extend to the narrow connecting strips 15 whichconnect the adjoining oflset ends of he reflector strips. By tilting thelamp body or by varying the angle of the reflector strips, the beam oflight may be inclined to strike the road at the proper angle, thefilament shielding wall and the lamp reflector 13 being of suflicientextent to pre- Vent exposure of the filament at the front of the lampwhen the lamp is thus tilted.

' What I claim is:

1. A headlight construction comprising a lamp casing having asubstantially rectangular outlet for the beam of light and a lamp shieldat the lower edge of such outlet, a lamp in back of said shield and areflector at the rear of the lamp and con-' sisting of a series ofconcave reflecting strips arranged in offset relation and extendingsubstantially horizontally and straight across the lamp casing, wherebyto provide a beam of light of uniform width in its vertical dimensionsbut having a diverging formation in its horizontal dimensions.

2. A headlightconstruction comprising a lamp casing having asubstantially 1'ec tangular outlet for the beam of light, a

lamp shield at the lower edge of such outlet,

a lamp at the rear of said shield and a reflector at the rear of thelamp and consisting of a series of concave reflecting strips arranged inoffset relation and extending substantially horizontall and straightacross the lame casing w ereby to provide a beam of lig t ofsubstantially uniform width in its vertical dimensions but having afan-like diverging formation in its horizontal dimensions, and areflector covering the forward side of the lamp and arranged to reflectthe light emanatin from the forward side thereof rearwar 1y against thebeam reflecting strips.

3. A headlight construction comprising a lamp casing having asubstantially rectang'ular outletfor the beam of light and a lamp shieldat the lower edge of such outlet, a lamp at the rear of said shield anda reflector at the rear of the lamp and consisting of a series ofconcave reflecting strips arranged in oli'set relation, said lamp beingset in a forwardly inclined relation to thereby expose a full clear sideof the same to the reflecting stri )s and the lower forward side of thelamp icing covered by a reflectin medium.

in testimony whereof I afiix my signature.

WILLIAM H. SGHOONMAKER.
